    Without knowing any details it would be difficult to make any judgement but from the set up you have to wonder whether they are grinding-out or grinding-in the flat spots!

    Sadly am not able to view the video due to it being firewalled, but I have certainly heard of wheelflats being 'dressed' with a grinder to remove the worst of any burrs etc, and then allowing the flats to basically run out in service, relying on track contact and braking to help smooth things out. Before anyone jumps to any conclusions this was on the mainline network and was supervised by a qualified expert in such matters ...

    I wonder what all that grinding dust did to the wheel bearings?

    Grinding off the burrs created by wheelflats is a procedure that I have carried out on a couple of occasions whilst working for BR and in preservation. Of course the action taken very much bepends on the severity of the actual flats. Very bad flats would require a visit to the wheel lathe.

    Much the same as all the dust that they encounter every day travelling.
